To-all whom it may concern. I

Be it known that I, STEWART C. Cour, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented new and useful Improvements -"in Skelp- Charging products; but my invention may be used for various other purposes;

The objects of this invention are to provide a rapi'd, simple and positive means for conveying skelp or other blanks of a mag? netic or magnetizable nature by the use of a magnet carried by a suitable frame-work or table.

Referring to the accompanying drawings, Figure 1 is'a longitudinalvertical section through the shaft on which the conveying magnet is mounted; Fig.2, an end elevation of a structure embodyin my invention, parts being broken away; ig. 3, a plan of the same, parts. being'broken awa and Fig. 4, an elevation showing the en 0 posite that shown on F igt 2, a portion-o. the furnace being shown in section.

On the drawings, 1 represents a pair of rails on which'the wheels 2 of the charging :table 3 travel.

4 is a portion of a heating furnace across and forth. The top of the table has two levels, the upper or storage level 5 being the one on which the skelp 6 is piled preparatory to bein transferred to the lower level. The ske p on the upper level lie parallel to the direction in which they are to be charged into the furnace. They are moved laterally by workmen or by any suitable means so as to cause them". to reach their proper position on the lower level now to be described. The said lower level which may be at any desired distance below the upper level is shown parallel to the same. It has the conveying trough or-channel 7 open upwardly, there being in the bottom of the channel a number of transverse rollers 8 on which the skelp travel with but little friction during the chargin operation n order to-lighten the work 0 the charging magnet.

At the end of-the charging channel or bed 7 I place one or more rotary chargers 9,

having its axis of rotation transversely of the.- direction in which the skelp is to be ward the furnace 43 The charger. 9 is a horizontal cylinder composed ofv the two hollow end members or caps 12 composed of magnetizable inaterialfand an intermediate member 13 composed of non-magnetizable material, such as brass. The members '12 have theiropposing or adjacent ends" each provided with a cavity or hollow 14 concentric with the axis-of thecharger so that the shell or annular wall 15 shall be of uniform thickness. The adjacent ends of the shells 15 are separatedslightly to form the annular gap 16 in the magnetic circuit to be described presently. This gap is made wider near the interiorv surface of the shells by forming the interior shoulder-s17 in the shells. The members 12 are connected together by the brass connector 13 which has its ends in the hollows 14 and the central portion 'of its periphery in the annular space between the ends of the shells 15.

The'ends of the charger 9'are supported by the alined shafts 18 and 19 composed of magnetic material and. having their axes in line with the axis of the charger. The opposing ends of these shafts extend through central openin s in the ends of the members 12 and into t e ends of the memher 13 but are separated by a wide gap. The shafts are keyed to the members 12 and 13. as shown} in Fig. 1. I

The shafts 18 and 19'tnrn in the vertical bearings 20 and 21, respectively, supported bythe table, and composed of magnetizable material. The lower ends of the bearin s 20 and 21 are connected together by t e fixed core 22 of the windin 23. The bear-' ings 20 and 21 constitute t e end members of a magnetic frame, its magnetic circuit including the'core 22, the end members or bearings 20 and 21, the shafts 18 and 19, and the members 12. This circuit is open at the annular gap 16 across which the flux flows when the winding 23 is energized, that gap is largely diverted so as to travel transversely through the skelp at and'about its line of contact with the periphery of the magnet. The rotary charger 9 exerts, therefore, a great tractive or adhesive effect on the skelp and causes it to be charged into the furnace at the surface velocity of the magnet. -The electric motor 10 can, as is well known, be controlled so as to give the skelp such initial, final, and intermediate charging speeds as may prove best. After a skelp has been charged into the furnace, the charging table 3 is'moved on. the rails 1 to the desired position for charging another skelp. into the furnace, I

My invention dispenses with a large number of men required for the hand charging of skelp; eliminates the danger incidental to the present style of chargers; and saves large losses of time and power required by said chargers. f

It is obvious that more than one magnetic feeder opcharger may be used at selected places along the trough, or near the one shown.

I claim:

1. The combination of a charging table, a rotary charging roller carried by the table and having a magnetizable periphery with an annular gap, a winding stationary relatively to the table, a magnetic circuit energized by the Winding and including the said charging roller, the latter being arranged externally of the winding, and means for rotating the roller.

2. The combination of a table, a magnetizable roller having an annular gap, a winding stationary relatively thereto, a magnetic circuit energized by the said winding and including th'e'saidroller, the roller belng arranged With the said gap transverse of the flux through the roller, and means for rotating the roller.

3. The combination of a table, a trough thereon, ama etizable roller supported by the table an having its'axis of rotation transverse of the trough and its periphery.

transverse of the trough and its periphery arranged to be engaged by magnetizable material in the trough, a winding stationary with respect to the table, and a magetic circuit energized by the winding and includingthe roller arranged lengthwise therein,

there being a peripheral gap in the roller.

5.- The combination of a table, a feed roller having opposite axially-alined shells of magnetizable material separated by a peripheral gap, non-magnetizable materlal connecting the shells, means for rotating the roller, a magnetic circuit including the roller arranged lengthwise therein, and a winding stationary with respect to the roller for energizing the. said circuit.

6. The combination of a table, a magnetizable roller having an annular gap, a winding stationary relatively to the table, a magnetic circuit energized by the w nd ng and including a fixed core in the winding and the said roller, the gap in the roller being transverse of the flux through the roller, and means for rotating the roller. i

7. The combination of a table, a feed roller thereon. a stationary Winding, a mag-- netic circuit, including a core in the win ing, arranged to transmit lines' of magnetic force through the roller and into. magnetizable material on the roller.

8. The combination of a table, a'rotatable' cylinder supported by the table and having its axis of rotation transverse of the table and its periphery arranged to be engaged by the magnetizable material, a winding stationary with respect to the table, and a magnetic circuit energized by the winding and including the cylinder.
